[R] r version 2.1.0 and graphics in mac os 10.3.9

[Luis Borda de Agua]

I use mac os 10.3.9 and I've installed in my computer R 2.1.0 (I  
believe this is the latest R version).

Although it works alright when I open R by clicking in the R icon, I  
cannot use the graphics facility when I open R from a X-terminal window  
(or x-11 window).

In fact, when I try to open R I get the message that I pasted below.
Is this a R bug?
Is R assuming that I should have the latest Mac OS Tiger installed?
Or is it a problem related to my computer only?

I did not have this problem when I used a previous version of R (I  
don't know which one was).

Thank you in advance for your help.

Luis BA.
